Salutare.
Aveam mai demult niste un firewall pe CentOS in care aveam:
for s in ${lista}
do
iptables -A FORWARD -p tcp -s ${s} --match multiport --dports 80,443,21
-m string --string '.exe' --algo bm -j DROP
iptables -A FORWARD -p tcp -s ${s} --match multiport --dports 80,443,21
-m string --string '.zip' --algo bm -j DROP
iptables -A FORWARD -p tcp -s ${s} --match multiport --dports 80,443,21
-m string --string '.EXE' --algo bm -j DROP
iptables -A FORWARD -p tcp -s ${s} --match multiport --dports 80,443,21
-m string --string '.ZIP' --algo bm -j DROP
iptables -A FORWARD -p tcp -s ${s} --match multiport --dports 80,443,21
-m string --string '.TORRENT' --algo bm -j DROP
iptables -A FORWARD -p tcp -s ${s} --match multiport --dports 80,443,21
-m string --string '.torrent' --algo bm -j DROP
iptables -t nat -A PREROUTING -i eth1 -p tcp --match multiport --dports
80,21 -s ${s} -j DNAT --to 192.168.0.254:8080
iptables -t nat -A POSTROUTING -p tcp -o ${INTERNET} --match multiport
--dports 23,25,53,110,443,5000,5001,5050,5100 -s ${s} -j SNAT --to-source
${NAT}
iptables -t nat -A POSTROUTING -p udp -o ${INTERNET} --match multiport
--dports 53,5000,5001,5050,5100 -s ${s} -j SNAT --to-source ${NAT}

Vroiam sa o folosesc din nou ca sa blochez fisierele respective dar am
constatat ca nu mai merge.
Am incercat sa fac si pt. fiecare port in parte (sa renunt la --match
multiport) si nu a mers.
Nu as vrea sa folosesc squid-ul ca sa blochez fisierele astea. (daca mai
merge blocat prin iptables)
Multumesc anticipat.
